The ADS5295 is a low-power, 12-bit, 100-MSPS, 8-channel analog-to-digital converter (ADC). Low power consumption and integration of multiple channels in a compact package make the device attractive for very high channel count data acquisition systems.

Serial low-voltage differential signaling (LVDS) outputs reduce the number of interface lines and enable high system integration. The ADC digital data can be output over one or two wires of LVDS pins per channel. At high sample rates, the two-wire interface helps keep the serial data rate low, allowing low-cost field-programmable gate array (FPGA)-based receivers to be used.

The device integrates an internal reference trimmed to accurately match across devices. Best performance is expected to be achieved through the internal reference mode. However, the device can be driven with external references as well.

Several digital functions that are commonly used in systems are included in the device. These functions include a low-frequency suppression mode, digital filtering options, and programmable mapping.

For low input frequency applications, the low-frequency noise suppression mode enables noise suppression at low frequencies and improves signal-to-noise ratio (SNR) in the 1-MHz band near dc by approximately 3 dB. Digital filtering options include low-pass, high-pass, and band-pass digital filters, as well as dc offset removal filters. The device also provides programmable mapping of the LVDS output pins and analog input channels. For applications where the 12-bit ADC SNR is not required, the ADS5295 can be configured as an 8-channel, 10-bit ADC with 10x LVDS serialization to reduce the output data rate.

The device is available in a 12-mm × 12-mm QFP-80 package. The ADS5295 is specified over the –40°C to +85°C operating temperature range.

ADS5295EVM — ADS5295 평가 모듈

ADS5295 평가 모듈(EVM)은 ADS5295 저전력, 12비트, 100MSPS, 8채널 아날로그-디지털 컨버터(ADC)의 성능을 입증합니다. ADS5295는 소형 패키지에서 저전력 소비와 다채널 통합을 제공하므로 채널 수가 매우 많은 데이터 입력 시스템에서 매우 유리합니다. 직렬 저전압 차동 신호(LVDS) 출력을 통해 인터페이스 라인 수를 줄이고 시스템 집적 수준을 높일 수 있습니다. ADC 디지털 데이터는 채널당 LVDS 핀 1~2 회선을 통해 출력할 수 있습니다. 샘플 레이트가 높은 경우 2회선 인터페이스를 통해 직렬 (...)
